Vertical cartridge pump with frequency converter
Thread Content
Can a vertical bag pump be equipped with an inverter? Are there any requirements regarding frequency? Can an inverter control multiple pumps at the same time?
Variable frequency can be added. Generally, the adjustment range of variable frequency is within 30% of the load; those without back pressure can be adjusted to full load. For pumps with high power ratings, the frequency of the inverter cannot be too low; it should be at least around 20 Hz. If the frequency is too low, the inverter generates excessive heat. I have never seen an example of a variable frequency drive controlling multiple pumps at the same time.
You should first check whether the motor of your pump operates at fixed frequency or variable frequency, before deciding whether to install an inverter. Once the speed decreases, the motor’s cooling efficiency will be very poor; think carefully before making a decision
